RFM02-868-D
QUASAR RFM02-868-D 发射器模块, 5DB, 868MHz
RFM02 is a low costing ISM band transmitter module implemented with unique PLL approach. It works with FSK modulated signal ranges from 433/868/915MHZ bands, comply with FCC, ETSI regulation. The SPI interface is used to communicate with microcontroller for parameter setting. RFM02 works with RFM01 receiver module. At 433MHZ band, the pair of module can work up to 300m in the free open air.
